The Model Method for Upper Primary
The document discusses the Model Method, an instructional approach for upper primary students. It provides examples of word problems modeled with bars or arrays to represent the relationships and operations in the problems. The examples demonstrate modeling problems for up to 8 days to help average students, and using algebra to model problems for 3-4 days for advanced students. It also discusses using differentiated instructional strategies and modeling techniques for struggling learners.
